中文摘要:

      Y-3D井是土库曼斯坦阿姆河右扬古伊气田构造带上的一口大斜度开发井。针对该井上部地层大井眼泥岩段存在易泥包、易垮塌及携砂困难、中部井段长段膏、盐层对钻井液的污染、高温对钻井液性能的影响及大斜度定向钻进中的润滑防卡及下步地层易喷易漏及高含H2S等技术难题,通过钻井液体系和技术措施优化,使钻井液性能满足了钻井工程、地质录井和保护油气层的要求,实现了了安全、优质快速钻井。

英文摘要:

      Y – 3D well is turkmenistan amu darya right young gouy field of a big slope structure with development well. Against the big hole well strata mudstone easily balling, easy to collapse and carrier of difficulties, the central well long period of cream, salt drilling fluid pollution, high temperature effect on the properties of drilling fluid and high Angle directional drilling in the lubrication and preventing formation next easy to spray easy to leak and high content of H2S and other technical problems, by optimizing drilling fluid system and technical measures to drilling fluid performance meet the the requirements of drilling engineering and geological logging and reservoir protection, to achieve safety, high quality fast drilling.
